I'm trying to install an amp to power a kicker sub in the factory enclosure, and have one last question. I plan on using a low level output converter, and the only snag is where to splice the wires. I plan on splicing from the front speakers, but should I splice them before or after the factory amp? Thanks!

If you're using a LOC then I would splice downstream of the amp, because the factory amp/HU build does all sorts of weird and wonderful things across CANBUS. It might well work splicing upstream of the amp, but downstream you can guarantee that it's a straight line output with no risk of causing any issues with CANBUS.

You said that you planned on using a level/line output converter. This takes an amplified signal, and converts it into a non-amplified signal that is ready for presentation to an amplifier. It means that you can safely connect an amp downstream of a speaker level output from another amp or directly from a head unit. Why were you planning on using the LOC if not for this purpose?

No reason not to do it yourself, that's what this place is for.

Okay, makes perfect sense now. I'm planning on using the LOC to introduce the RCA type connections to connect to the amp. I have read to use the front speakers, so I was planning to splice it in right by the amp under the steering wheel.
